FIELD OF THE INVENTION

The present invention belongs to the technical field of construction; more particularly, it belongs to the technical field of modular systems for sustainable dwelling construction.

BACKGROUND

Prefabricated homes today have a fairly high demand from people who need to build efficiently and with reduced operating times, they also have a great need to be affordable and family homes in different areas, whether rural or urban, the prefabricated house has the advantages, for example that the construction can be carried out throughout the year without the weather being a factor that prevents its advance, they are prefabricated in a production line in the factory with its respective assembly line, Greater building efficiency is achieved by being easy-to-assemble systems, allowing a man to perform more tasks in a day's work, construction execution time is reduced, a building is achieved with greater cleanliness and with minimal hidden defects, by The units being almost completely pre-finished from the factory, it is achieved that the partitions, doors, accessories, equipment and windows, among others, are and install precisely as there are no errors due to misalignments and/or collapses, the finishes are implemented more easily due to the precise alignment of the precast elements and it can also be mentioned that the building is more economical being that the typical factory salaries are substantially lower than field wages.

Each manufactured dwelling unit is typically built with a separate floor and roof. Therefore, when units are stacked on top of each other on site, the floor in an upper unit is placed on the ceiling of a lower unit. This results in excessive loading on the part of the structural joist members. This is different from conventional site construction that uses the same joist for both the upper floor and the lower ceiling between two modules.

Various designs for floor/ceiling units are described in U.S. Pat. Nos. 1,886,962, 3,510,997, 3,724,141, 4,211,043 and 5,575,119. Each of these designs are basically hybrid panel construction methods; that is, the single-unit floor functions as the single-unit roof, as a standard construction on site builds multi-story structures. Someone can go to any construction site where a multi-story complex is being built. However, in such prior art designs, the floors and ceilings of the constructed dwelling units are not being finished, but on site. Therefore, these panel assemblies still require extensive on-site finishing, including wall and ceiling finishes, floor coverings, and installation of cabinets and accessories. Furthermore, most of these panels are constructed of concrete, a very difficult material to use for mass production.

However, because the modules are presumably shipped to site in standard flat-surface racks, the roof portion of the upper “U” cannot be finished, for example painting or tapping, until after the modules are erected. in the place. Consequently, since the roof must be finished on site, the degree of factory finish of the walls, floors, and fixtures is limited due to the roofs that were shipped and completed. Although this proposed construction method theoretically eliminates redundancy of wall and floor/ceiling materials, it does not account for.

The prior art references describe the use of vertical steel tubes in combination with the units to provide the load capacity. For example, U.S. Pat. Nos. 3,925,679 and 4,592,175 disclose tube assemblies that act primarily as reinforcing agents on the unit walls. U.S. Pat. Nos. 3,927,498 and 5,755,062 disclose construction techniques where tubes are used. U.S. Pat. No. 4,470,227 makes use of an angle as a temporary exterior reinforcement.

U.S. Pat. Nos. 4,723,381 and 5,528,866 offer the use of exposed vertical structural steel members for the outer support of assemblies. However, such a construction method lacks the possibility of proposing external supports to practical considerations of aesthetics, exposure to elements, and code constraints.

Modular buildings of more than one story are generally erected by first establishing the integrated units both horizontally and vertically, and then constructing and connecting, corridors, and stairs. This progression of setting first priorities in corridors, corridors and staircases has the problem that the more units are used especially the more units are used the more stacked, the harder it will be to keep them plumb.

Thus, it can be seen that there is a need for a load bearing assembly that can accommodate the pressures of stacked units, thereby relieving the exterior walls of increased load, in accordance with most building and safety codes, as well as having hydraulic elements that allow it to have a differentiation with respect to what is already known, providing a home with characteristics different from those commercially known that provide comfort and confidence to the final buyer as well as to the people involved in the manufacturing process

FIG. 32A illustrates an isometric view of a general diagram of the common hydraulic installation 600 of a house and in FIG. 32B an enlarged view of some connections of the temperature control system 612 is illustrated; The water is commonly stored in a cistern 601 and is pumped to a tank 604 through the water fill line from the tank to a tank 603; a water pump 602 is generally used to accomplish this. The water stored in tank 604 travels through the tank outlet line 605 and is distributed to two channels, the tank line to heater 607 and the tank line to the cold water tap 609; In order to obtain water at the desired temperature through the shower 615, the cold water 610 and the hot water 611 taps are commonly opened, regulating the flow of both until the combination gives us a desired water temperature. To prevent the water from being wasted while it exits through the showerhead 615 at the desired temperature, the control system 612 installed in the hydraulic system is illustrated, where it can be seen that, for this case, the water coming from the heater 606 through from the heater line to the hot tap 608, firstly, it is directed to the control system 612. This temperature control system registers the desired temperature indicated by the user through its display 618; if the water that is circulating through said control system 612, is not yet at a temperature equal to or greater than that indicated, the control system closes the solenoid valve 614 and opens the solenoid valve 613 directing the water through the line 616 to a water storage tank 617, preventing the same from traveling and leaving through the shower 615, preventing it from being wasted; Once the temperature of the water circulating in the control system 612 is at a temperature equal to or greater than that indicated by the user, the solenoid valve 613 closes and the solenoid valve 614 opens, allowing the flow of water now it is directed towards the shower 615. At the same time that this happens, an opening signal 620 is sent to the solenoid valve 619 of the storage tank 617, allowing it to empty releasing the water contained towards the shower 615 and thus be ready to go back to its storage function.

By making the system com to fully store the water that was stagnant in the hot water pipes, and do not allow it to flow out of the 615 showerhead until it is at the desired temperature, it is avoided that it is spilled into the drains, achieving considerable savings in m3 of water consumption for toilet for each user.

FIG. 32B illustrates an enlarged view of the water storage tank 617 connected to the solenoid valves 613 and 614, it can be the same or two can be working independently, in addition to the display 618.

FIG. 33 illustrates an isometric view of the hydraulic system in conjunction with the temperature control system 612, only that in this case the water that travels through the pipes and/or hot water line 608 at the moment of opening it, is recirculated towards cistern 601 instead of being recirculated into a storage tank. Achieving with this to avoid wasting water by not being thrown down the drains while it is heating. The cistern 601 is illustrated, the pumping of the water through the pump 602 that travels through the line 603 towards the tank 604, the line 605 from the tank can be seen, which in turn is divided into two branches, these being: the line of cold water 609 that travels to the tap 610 and subsequently to the shower 615, and the hot water line 607 that enters the heater 606 and which is the one that is modified for the purposes of the present invention.

It is illustrated how the line 608 travels to the hot water tap 611 which in the same way is first directed to the temperature control system 612 before being sent to the shower 615. For this case if the control system 612 detects that the water It is not yet at the desired temperature and indicated by the user through its display 618, it operates by opening the electro valve 613 and closes the electro valve 614, allowing the water flow to be directed through the outlet line of the water system. control 616 returning to cistern 601; If the control system 612 detects that the temperature is equal to or greater than that indicated on the display 618, the system closes the solenoid valve 613 and opens the solenoid valve 614, allowing the water to now flow into the showerhead 615, thereby avoiding the waste of it while it is heated. Instead of directing the water stored in the pipes to cistern 601, the system has the option of directing the water through line 616 to other areas for other purposes such as toilet tanks.

FIG. 34A illustrates an isometric view of the hydraulic system in conjunction with the temperature control system 612 as in FIG. 32A, only for this case a water saving mechanism is added to the system that not only prevents it from being wasted when waiting for it to come out at the desired temperature, it also integrates a motion sensor with electro valve 621 that when it does not detect movement of a user, in a configured range; the sensor with solenoid valve 621 prevents the flow of water through the showerhead 615 from being wasted, this while the user soaps and shaves, or does some other activity. Also illustrated is a strainer 622 with an electro valve that, by means of a user indication through the display 618, the strainer 622, activates the solenoid valve it contains, directing the water to the storage tank 617, through the return line to the strainer 623, achieving with this that the user can remain enjoying the sensation of the water inside the shower simply for pleasure or for play, avoiding that a large percentage is wasted since it is being recirculated. As this function is given at the end of the toilet, the water is kept clean, however, an optional 624 filter can be installed if desired.

FIG. 34B illustrates an enlarged view of the storage tank 617, the hot tap heater line 608, which is connected to the general control system SC for temperature control 612, which contains a desired temperature indicator display 618, connected to the tank outlet solenoid valve 613 and a shower outlet solenoid valve 614. Also illustrated is the cold water faucet 610, hot water faucet 611, showerhead 615, control system outlet line to water tank 616, the shower outlet solenoid valve 619, the control system cable to the tank outlet solenoid valve 619, the motion sensor 621, the strainer with solenoid valve 622, the return line from the strainer to the tank and/or cistern 623 and the optional filter 624.

FIG. 35 illustrates another modality of a general diagram of the common hydraulic installation 700 of a house where water is commonly stored in a cistern 701 and is pumped to a tank 702 through the water fill line 703 of the cistern. to the tank, using a water pump 704. The water stored in tank 702 travels through outlet line 705 and is distributed to two branches if These include line 706 from the tank to the water heater 707 and line 708 from the tank to the cold water tap 709; In order to obtain water at the desired temperature, through the shower 710, the hot water tap 711 is commonly opened first, and later the cold water tap 709, regulating the flow of both until the combination gives us a temperature of the desired water; while the hot water reaches the showerhead 710 and to prevent it from being wasted, the control system 712 containing the showerhead 710 is schematized and is connected to the combined water line 713; Said control system 712 activates, by means of a wireless signal, a re-circulating pump 714. Lastly, the hot water line 716 and the check valve 715 that prevents the return of water to the tank 702 can be seen.

FIG. 36 illustrates an isometric view of the hydraulic system in conjunction with the control system 712 as in FIG. 35, only for this case an enlarged view of the cold water taps 709 and the hot water tap 711 together with a temperature sensor 717 inserted inside the combined water line 713. The temperature sensor 717 has the function of detecting the temperature of the water that passes through the pipes so that the system comes into action.

FIG. 37 illustrates an isometric of the hydraulic system in conjunction with the control system 712 as in FIG. 35, only for this case an enlarged view of the control system 712 that contains its own shower 710, the water taps is illustrated. cold 709 and hot 711, as well as heater 707 and recirculation pump 714.

When the user opens the hot water faucet 711, the water begins to circulate through the hot water line 716 and tries to exit through the shower 710 when circulating through the combined water line 713; As soon as the temperature sensor 717 detects that the water is still cold, the control system 712 closes a solenoid valve inside it, preventing the water from flowing out of the showerhead 710 and at the same time sends a wireless signal to the recirculation pump 714; This pump makes the water flow recirculating inside the hot and cold water lines, preventing it from going out through the showerhead 710 and being wasted when being flushed down the drain. Once the sensor 717 detects the hot water, it sends a signal to the control system 712 causing it to activate the solenoid valve inside it and allow the hot water to flow through the combined water line 713 and out through the showerhead 710; simultaneously the control system 712 sends a wireless signal to the recirculation pump 714 to stop pumping.

FIG. 38 illustrates an isometric of the hydraulic system in conjunction with the control system 712 as in FIG. 35, only for this case an enlarged view of the control system 712 as well as the heater 707 and the circulatory pump 714 is illustrated.

The control system 712 contains an electromechanical system with a liter counter with a 719 digital display that shows the number of liters that are circulated through the 710 shower to make the user aware of the number of liters used in each shower; Likewise, a 720 digital display is shown that shows the temperature at which the system was programmed to activate recirculation. Also illustrated are both the wireless signal system 721 of the control system 712 and the wireless signal system 722 of the recirculation pump 714 whose function is to send the pumping on and/or off signal.

Finally, the presence sensor 718 is illustrated whose function is to prevent the passage of water through the showerhead 710 when the user goes out of range by stepping aside to lather or perform some other activity.

FIG. 39 illustrates the block diagram of the electronics that make up the control system, this system is made up of two modules, which is the control module 730 and the recirculation module 739.

Considering the control module 730 is the one that is in charge of controlling the water circulation and that corresponds to 712 in FIG. 35, this module is made up of a microcontroller that is in charge of processing the information received from the temperature sensor 733 which is the sensor 17 of FIG. 36 and with which the value of the water temperature in the mixing pipe is received, which when detecting by means of the sensor 735 that a user has opened the taps 709 and 711 to bathe, then The microcontroller activates an electro valve that prevents the passage of water, immediately activating a WIFI module 738 by means of which an activation signal of the recirculation pump 714 of FIG. 35 is sent, as already described above, when the sensor The temperature sensor detects that the water in the mixing pipe is at the temperature determined by the user, then the microcontroller 731 sends the signal to the WIFI module 738 to stop the recirculation pump and in turn deactivates the solenoid valve of the shower so that the water flow leaves the shower in a normal way. Taking into account the data from the sensors, and when processing the information received in the microcontroller 731, it shows information regarding the water temperature through the control of the display 737, which is responsible for displaying said information on the display 720. of FIG. 38, while the amount of water consumption in liters is shown by means of the display control 736 which is in charge of showing the information on water consumption on the display 719 of FIG. 38.

Considering the recirculation module 739, it is made up of a WIFI module 740 which receives the signal from the WIFI module 738 when the pump needs to be turned on, so that the detection of said signal is sent to the microcontroller 741 where it is processed and the signal corresponding to a power interface 742 is generated with which the pump 743 corresponding to the pump 714 of FIG. 35 is turned on, when the water in the mixing pipe reaches the determined temperature, then the pump is deactivated to maintain the water flow as normal.

In one mode, the microcontroller 731 is in communication with a presence sensor 734 by means of which the presence of a user under the shower is monitored and that when it is removed from it the solenoid valve is activated with which the flow of water in the shower is blocked until the presence of the user under the shower is again detected.

FIG. 40 illustrates the steps that are carried out to control the water-saving recirculation system in showers, in such a way that in step 744 the microcontroller 731 detects the flow of water when a user opens the taps 709 and 711, this by means of the flow sensor 735, and to initiate the flow of water, then the microcontroller 731 by means of the temperature sensor 733 detects the temperature of the water in step 745 and compares it with the value determined by the user and if the temperature is not within the determined value, then the microcontroller activates a solenoid valve that is in the shower to prevent the flow of water from leaving the shower, immediately sending a signal in step 746 to activate the water recirculation system, which is performed by means of the recirculation pump 714, causing the water to flow inside the same pipe, as already described, for later in step 747 it is verified if the t The temperature is already within the determined value, which in the event that it is not within the determined value, then it returns to step 745 to continue detecting the water temperature and maintain the recirculation of the water within the same pipe, in the case that in 747 the value of the water temperature is determined that is equal to the determined value, then the recirculation pump is deactivated in step 748 and the shower solenoid valve is deactivated so that the flow of hot water flows through she.
